Protests continued in the troubled St. Louis suburb of Ferguson, Missouri, Wednesday night – as emotions ran high over the death of 18-year-old Michael Brown on Aug. 9.

On Wednesday, protestors were mostly calm and generous, offering water to strangers and mingling peacefully. After 8 p.m., as marches began, protestors shouted, "Hands up! Don't shoot!" and police began to usher them out of the way.

"This was the spark," Norita Bonaparte, 40, a Ferguson resident, tells PEOPLE. "It put more fuel to the fire. St. Louis really is the 'Show Me State' and they're not going to stop until they feel justice has prevailed. But if it doesn't, that's what I'm worried about. It's not going to be a nice scene."

Wilson, who has been on administrative leave since the shooting, has not yet been indicted in Brown's death.

"This incident, only God knows why it happened," Bonaparte says. "But it has been exposed. If he [Wilson] doesn't get indicted, if nothing happens to him – I don't think it's going to be good. I will have to pack up and [leave] for a while."
